Sure it is, SA. The effective demand problem is only one piece. The other is rising organic composition of capital (Robert Brenner unfortunately does not foreground this) and declining rates of profit in value-producing activities, from the early 1970s onwards. And hence from the early 1980s, a variety of spatio-temporal displacements of overaccumluation are invoked. David Harvey's work sets this out as well as anyone's.
